The object of the present invention is an atmospheric gas burner (300) for cooking tops (400), in particular household cooking tops (400), where the air-gas mixture is obtained by the effect of the gas supply pressure using the principle of the tube ejector (10; 310) of Venturi that has a sufficient quantity Z≧1 of ejectors (310) to supply, globally, the maximum power (Wb) provided for the same burner (300). Each of said ejectors (310) develops on a horizontal plane, has the axis of its diffuser (315) which in the first stretch (322) is substantially rectilinear and tangential to a circle with centre on the central axis (324) of said burner (300) while in the second stretch (323) gradually bends substantially as a spiral towards the same central axis (324), leads, downstream of said diffuser (315), to a converging channel (327) which gradually bends vertically upwards and which, in turn, leads to one or more diffusion chambers (328) to which one or more flame spreading caps (318) act as a cover.
An atmospheric gas burner for cooking tops where the air-gas mixture is obtained by the effect of the gas supply pressure using the principle of the tube ejector of Venturi, comprising a quantity Z≧1 of ejectors able to supply, globally, the maximum power (Wb) provided for the same burner wherein each of said ejectors is configured to develop on a horizontal plane,
The atmospheric burner according to claim, 1, wherein when said ejectors are in a quantity Z≧2 they engage, according to said substantially tangential direction, on the outer circumferential wall in a plurality of sectors thereby forming at least for a first portion thereof, the second stretch of said diffusers, circularly distributed below said one or more flame spreading caps each of said sectors receiving one of more of said ejectors.
The atmospheric burner according to claim 21, wherein the plan pattern of said partitions is spiral-wise according to the lines that the flows of said mixture would take if said partitions were absent.
